WebA "gram" is the standard unit for mass. "Kilogram" is just 1 000 x the mass of the gram. To multiply by 1 000, all you have to do is move the decimal point to the right 3 times because there are 3 zeros, and to divide by 1 000 you move it 3 times to the left. For example: 3 kilograms = 3 000 grams 3 grams = 0.003 kilograms WebThe gram formula mass of a compound is the amount of that compound that has the same mass in grams as the formula mass in atomic mass unit.

Consider beryllium and uranium. Their abundances are very similar when looked at in terms of mass: 1.9 parts per million (ppm) for beryllium versus 1.8 ppm for uranium. In terms of molar abundance, they aren't so similar.
WebJan 31, 2024 · Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol. Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol. This is the number of moles in 100 g of water.
